Rio Tinto’s Zulti South Project Signals Confidence in South Africa’s Mining Industry

Global mining giant Rio Tinto has announced plans to restart the $473 million Zulti South project, a move widely viewed as a strong vote of confidence in South Africa’s mining sector and long-term mineral investment prospects.

The project, part of the operations of Richards Bay Minerals (RBM), is expected to extend the life of the mine until 2050, strengthening the country’s position in the global minerals supply chain.

RBM, which is 74% owned by Rio Tinto, mines mineral-rich sands along the coast of KwaZulu-Natal and produces valuable industrial minerals such as zircon, rutile, ilmenite, and titanium dioxide.

These minerals are widely used in the manufacturing of a broad range of products, including paints, medical equipment, sunscreen, and smartphones, highlighting South Africa’s strategic role in global industrial value chains.

According to the Department of Mineral and Petroleum Resources (DMPR), the project restart signals renewed investor confidence in the country’s mineral resources sector.

“This significant capital commitment signals renewed investor confidence in South Africa’s mineral resources sector and enhances collaboration between industry, government, and host communities,” the department said.

The Zulti South project was previously halted in 2020 following unrest in surrounding communities. However, authorities say improved cooperation between government, traditional leaders, and local communities has created conditions for the project to move forward again.

The DMPR noted that partnerships between mining companies, government institutions, traditional leadership structures, organized labour, and host communities are critical for ensuring the sector contributes to inclusive economic growth and sustainable development.

“Through partnerships of this nature, the mining sector can leverage private-sector investment to unlock inclusive economic growth,” the department stated.

Construction of the project is expected to begin in the first quarter of 2026 and is projected to take approximately 30 months to complete.

Once operational, the Zulti South development is expected to create employment opportunities, support skills development programs, and contribute to the socio-economic development of mining-affected communities in the region.

Officials emphasized that maintaining stability, responsible mining practices, and strong social partnerships will remain essential for unlocking long-term value from South Africa’s vast mineral resources while ensuring that communities benefit from mining activity.

The restart of the Zulti South project comes at a time when South Africa is seeking to attract greater investment into its mining sector, particularly as global demand rises for minerals used in advanced manufacturing and energy technologies.
